厌氧膜生物反应器研究与应用概述(代序言)

A review of recent advancements in the research and application of anaerobic membrane bioreactors

在污水资源化及双碳目标驱动下,开发节能、低碳、资源回收型处理技术是污水和废弃物处理领域的重要发展方向。将厌氧消化与膜分离结合的厌氧膜生物反应器(anaerobic membrane bioreactor,AnMBR)具有能耗低、可回收能源以及处理水质较好等优势,在过去40 a已经在工业废水、有机固体废弃物以及城市污水的资源和能源化领域开展了广泛的研究。与传统厌氧消化技术相比,厌氧MBR通过膜分离过程延长了污泥停留时间,维持反应器中高生物量,促进了物质分解及甲烷转化,极大提高了厌氧消化的效率。为了推进厌氧MBR技术的工程化应用并提供技术与理论的支撑,《环境工程学报》编辑部邀请李玉友、盛国平、李倩3位教授组织了“厌氧MBR技术与有机废水资源化”专题,综述了厌氧MBR的发展历程、主要研究团队、在有机废水资源化中的应用及最新研究热点,作为该专题的代序言。

In response to the imperative of wastewater resource utilization and the'carbon peaking and carbon neutrality strategy,'the development of energy-saving,low-carbon,and resource-recovery treatment technologies emerges as a crucial focus in the wastewater and waste treatment.Over the past 40 years,the anaerobic membrane bioreactor(AnMBR),which integrates anaerobic digestion with membrane separation,has garnered significant attentions.This technology boasts advantages such as low energy consumption,energy recovery,and excellent permeate quality,leading to widespread research across various sectors including industrial wastewater,organic solid waste,and municipal wastewater resource and energy utilization.Compared to conventional anaerobic bioreactors,AnMBR significantly enhances digestion efficiency by extending sludge retention time through membrane separation,thereby maintaining high biomass levels in the reactor and facilitating substance degradation and methane conversion.In a bid to advance the engineering application of AnMBR technology and offer technical and theoretical support,the Chinese Journal of Environmental Engineering has commissioned three professors—Li Yuyou,Sheng Guoping,and Li Qian—to organize a special subject on'AnMBR Technology and Organic Wastewater Resource Utilization.'This paper serves as a preface to the topic,summarizing the development history of AnMBR,highlighting key research teams,outlining its applications in organic wastewater resource utilization,and presenting the latest research hotspots.
